 |
|
Since xen was mainlined into the vanilla kernel a few months ago I've attempted on a few occasions to locate the xen specific section in Kconfig without much luck. I've been trying to find the config selections in 2.6.25 gentoo-sources and found the paravirtualized guest "PARAVIRT_GUEST=Y" however a xen specific section of kconfig that the official gentoo xen guide displays has so far eluded me 
specifically the following kconfig section needed to configure dom0 seems to be very well masked by menu dependancies http://www.gentoo.org/doc/en/xen-guide.xml offers that the following kconfig section should be available
| Code: | XEN --->
[*] Privileged Guest (domain 0)
<*> Backend driver support
<*> Block-device backend driver
<*> Network-device backend driver
<*> PCI-device backend driver
PCI Backend Mode (Virtual PCI) --->
[*] Scrub memory before freeing it to Xen
[*] Disable serial port drivers
Xen version compatibility (3.0.4 and later) |
nothing even remotely related to xen shows up in the config.
| Code: | hammer linux # cat .config |grep XEN
hammer linux # pwd
/usr/src/linux
hammer linux # eselect kernel list
Available kernel symlink targets:
[1] linux-2.6.21-xen
[2] linux-2.6.22-gentoo-r8
[3] linux-2.6.23-gentoo-r1
[4] linux-2.6.24-gentoo-r3
[5] linux-2.6.24-gentoo-r4
[6] linux-2.6.25-gentoo-r2 * |
Anyone know which config options need to be enabled so any xen specific menus needed to configure dom0 will display in kconfig? |

Actually there is no Xen dom0 support in the vanilla kernel. They just merged some domU code so Linux can boot inside a hypervisor.
You still need the Xen patches which are available only for selected kernel versions (although some distributors such as Novell have ported them to other kernel versions, IIRC), so you have to use xen-sources.
